Description

Technical Field

[0001] The utility model relates to the technical field of reactive power compensation cabinets, in particular to a dustproof and ventilated reactive power compensation cabinet. Background Art

[0002] Reactive power compensation, also known as reactive power compensation, is a technology that improves the power factor of the power grid, reduces the loss of power transformers and transmission lines, improves power supply efficiency, and improves the power supply environment in the power supply system. Reactive power compensation devices are usually installed inside the cabinet, so they are called reactive power compensation cabinets.

[0003] The internal structure of the existing reactive power compensation cabinet needs to dissipate heat during use to ensure that the temperature generated during the use of the internal power system is discharged. Usually, air circulation is used through the vents to dissipate heat. At the same time, dust in the air will also enter the inner cavity of the reactive power compensation cabinet. Therefore, the reactive power compensation cabinet needs to be dustproof while being ventilated.

[0004] For example, in a reactive compensation cabinet with application number CN202322423288.0, a plurality of positioning plates are fixedly installed inside the cabinet, a bevel rack is fixedly installed on the inner side of the plurality of positioning plates, the two sides of the support plate are slidably connected to the bevel rack, two motors are fixedly installed on the outer side of the support plate, the output shafts of the two motors pass through the support plate, and the output shafts of the motors are fixedly connected to bevel gears, the outer sides of the two bevel gears are meshed and connected to the bevel rack, and the reactive compensation device is fixedly installed above the support plate. The reactive compensation cabinet, by rotating the motor and then driving the inner bevel gear to rotate, the support plate slides along the bevel racks on both sides, and utilizes the motor to drive the support plate to slide up and down to adjust the height and the size of the internal space of the cabinet, so as to adapt to the installation of reactive compensation devices of different models and quantities, making the use of the reactive compensation cabinet more convenient.

[0005] The above patent proposes that the ventilation holes of the reactive compensation cabinet are mainly arranged at the upper and lower ends of one side of the cabinet door, and simple dust prevention is performed by embedding a mesh grille in the ventilation hole. Since some reactive compensation cabinets are usually arranged outdoors, there is a lot of dust and they are more affected by nature. It is difficult to achieve effective dust prevention effect by only setting a single layer of mesh grille.

[0006] Therefore, we propose a dust-proof and ventilated reactive power compensation cabinet to solve the above-mentioned problems. Utility Model Content

The first filter mesh layer 4 is used for ventilation inside the reactive power compensation cabinet body 1. A protective component 5 is fixedly installed at one end of the cabinet door 3. The protective component 5 is used for shielding dust on one side of the cabinet door 3.

[0025] The protective component 5 includes a fixing mechanism 51 and a filtering mechanism 52 magnetically connected to the inner cavity of the fixing mechanism 51. A shielding mechanism 53 is embedded and fixed at the upper end of the fixing mechanism 51. The fixing mechanism 51 is configured to support the filtering mechanism 52 installed at one end of the cabinet door 3. The filtering mechanism 52 is used to perform preliminary filtering of external dust, and the shielding mechanism 53 is used in weather with heavy rain and snow.

[0026] The fixing mechanism 51 includes a concave frame 511 and an inner magnetic groove 512 opened in the middle of the inner wall of the concave frame 511. The inner wall of the inner magnetic groove 512 is pasted with magnetic patches (not shown in the figure) around it. A right-angle pull plate 513 is fixedly installed in the middle of the lower end of the concave frame 511, and a card slot 514 is opened on one side of the upper end of the right-angle pull plate 513.

[0027] A card insert 515 is fixedly mounted on the upper end of the top surface of the concave frame 511 , and a plurality of elastic elements 516 are fixedly mounted linearly and evenly spaced on one side of the inner wall of the card insert 515 , and a pressing plate 517 is fixedly mounted on one end of the elastic element 516 .

[0028] The filtering mechanism 52 includes a square iron frame 521 and a second filter mesh layer 522 embedded on both sides of one end of the square iron frame 521. The square iron frame 521 is magnetically connected to the inner cavity of the inner magnetic groove 512. The second filter mesh layer 522 is arranged at one end of the first filter mesh layer 4.

[0029] The mesh opening diameter of the first filter mesh layer 4 is smaller than that of the second filter mesh layer 522 . Impurities of different sizes can be filtered by staggering the mesh opening diameters of the first filter mesh layer 4 and the second filter mesh layer 522 .

[0030] In this embodiment: by fixing the concave frame 511 on one side of the cabinet door 3, by inserting the square iron frame 521 into the inner cavity of the inner magnetic groove 512 for magnetic fixation, by setting the second filter mesh layer 522 at both ends of one side of the square iron frame 521, it is used to filter and intercept larger dust during daily external use, while smaller dust is filtered through the first filter mesh layer 4, and the double-layer setting of the second filter mesh layer 522 and the first filter mesh layer 4 is used to perform double-layer filtration on the dust entering the reactive compensation cabinet, thereby reducing the entry of dust and improving the dust prevention effect.
